Vespers on Saturday (First Vespers of Sunday)

Saturday at Vespers – First Vespers of Sunday –

Based on the Jewish reckoning of time, evening belongs to the next day; Saturday night prayers are really Sunday prayers, thus “First Vespers”. On Sunday night, Vespers is known as “Second Vespers of Sunday”.

O Trinity of blessed light,
O Unity of princely might,
The fiery sun now goes his way;
Shed thou within our hearts thy ray.

To thee our morning song of praise,
To thee our evening prayer we raise;
O grant us with thy saints on high
To praise thee through eternity.

~Office hymn, O lux beata Trinitas
